Mercedes-Benz has unveiled its G63 AMG 6×6, a beastly luxury SUV with an insane 536-horsepower and six 37-inch wheels.

The vehicle is built alongside the regular G Class range at Magna Steyr’s operations in Graz, Austria, and was originally developed for the Australian military back in 2011.

Unlike the military version, which is fitted with Mercedes-Benz’s 3.0-liter V6 diesel, the G63 AMG 6×6 gets a twin-turbocharged 5.5-liter V8 with 536 hp.

Torque is a solid 560 lb-ft and is crucial in providing the shove required to haul the truck’s 8,322-pound curb weight. That power is sent through a seven-speed automatic transmission to one heck of a four-wheel-drive system.

The 6×6 G63 is still reasonably fast with a 0 to 100 km/h time of under six seconds and top speed of 160 km/h (100 mph – limited).

The G63 AMG 6×6 will be the second most expensive Mercedes-Benz model behind the new $457,000 (350,000 euros) SLS Electric Drive. The luxury SUV officially goes on sale in October. Currently, Mercedes is predicting sales of between 20 and 30 units annually.
